Behind the story a Druze officer is to command the IDF's Golani brigade is a surprising aspect:
According to figures from the IDF, the number of young Druze who serve in the IDF stands at 83%, which is higher than the percentage among the Jewish population. The relative number of Druze officers, noncommissioned officers and soldiers serving in the regular army is very high in proportion to the relative size of their community within the country’s total population. Most young Druze consider enlistment in the IDF as more than just an obligation and a necessary expression of their national loyalty. They see it as the sine qua non for advancement and integration into the country’s civil society.
There is a downside to this commitment:
While these young Druze have proved their loyalty to the state and fulfilled their responsibility with integrity, the state of Israel responds with ongoing prejudice, expressed mainly in discriminatory practices surrounding the distribution of development and infrastructure funding for their settlements.

I have long had an interest in the participation of minorities in civil-military service to a nation that is either not their own - in the imperial era - and today.

Somewhere I read that a large number of the Israeli Border Police, which has a national paramilitary role, are from minority groups and some recent footage showed a significant minority of black personnel (ex-Ethiopian Jews I expect).
